BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to image displays and signage, and more particularly, to displays of custom or arbitrary shape. Such shaped displays include channel letter displays, logo or design displays, curved or round displays, or other arbitrary shaped or unusual aspect ratio displays.

2. Description of the Prior Art

Displays have become increasingly more sophisticated, progressing from monochrome incandescent and LED to color to moving or changing to video quality displays, and from smaller to larger size, and with more elaborate content and control and driving systems. Channel letter type displays have progressed from simple neon or fluorescent light displays to video type displays. The construction of modern video-type channel letter or arbitrary shaped displays is typically accomplished using standard rectangular grid video components. Such use of rectangular grid video components is awkward and wasteful, and in some implementations lacks the full desired effect that channel letter shaped video components could provide. However, the production of shaped video components in arbitrary shapes is expensive and inefficient at present. Further, the rectangular grid video components and control system can be inadequate for creating the custom shaped displays that are becoming increasingly desired. Thus, there is need for efficient and cost effective production of arbitrary shaped displays.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

FIG. 1 and FIG. 2 illustrate prior art displays. Display 10 a is a prior art rectangular grid display. Graphical image 12 fills display 10 a. Letter shapes 14 a-14 d are displayed in an attempt to have the visual effect of a channel letter display. A display of this type lacks the visual effect of a true channel letter display. This prior art approach starts with display 10 a and covers or removes those portions that are outside of letter shapes 14 a-14 d. in FIG. 2, still another prior art approach is to fabricate channel letters 16 a-16 d using rectangular grid components. These alternate prior art approaches might produce channel letter displays with the general appearance of FIG. 2, which illustrates a display 10 b having channel letters 16 a-16 d and displaying graphical image 12. These alternate prior art approaches require significant custom fabrication and are not always even feasible, depending on the particular display type.

FIG. 3 illustrates an enlarged portion of the prior art display 10 b of FIG. 2. A rectangular grid of pixels 18 is shown, with pixels 18 p present in the display 10 b (shown with solid lines), and pixels 18 a which are absent or have been removed or covered (shown with dashed lines). Line 20 indicates the desired edge of a channel letter 16 of display 10 b.

FIG. 4 illustrates a channel letter display 22 with flexible pixel strings, the present invention, including shaped structure(s) 24. Although appearing similar to the prior art display of FIG. 2, the display of FIG. 4 is distinct in the manner in which it is produced and due to the presence of flexible pixel strings instead of prior art rectangular gridded Illustrated shaped structure(s) 24 can be channel letters 24 a-24 d or can be logo shapes, figure shapes, circular or curved shapes or sections, linear shapes, outlines, patterns, or combinations thereof. Channel letters 24 a-24 d spelling a company name, product name, place name, or other word or phrase may be desired. The channel letter display 22 can be a single shaped structure or can be multiple shaped structures 24, as shown. In this example, the shaped structures 24 are channel letters 24 a-24 d and the word “flag” is used for the channel letters 24 a-24 d and a graphical image 26 of a flag fills channel letters 24 a-24 d. in use, graphical image 26 may be any variety of images, designs, and so forth. For example, a moving (or animated) video image of a flag waving in the breeze could be “played” on channel letter display 22.

FIG. 5 illustrates an enlarged portion of the channel letter display 22 of FIG. 4. Portions of three flexible pixel strings 28 a, 28 b and 28 n are shown. Each channel letter 24 a-24 d comprises at least one pixel 30, but typically comprises many pixels. The individual pixels in each channel letter 24 a-24 d are in flexible pixel strings 28 a-28 n which are curvilinear strings with flexible connections 32 and arranged, by individual strings or group of strings, to form the shape of the channel letter or shaped structure(s) 24. Any convenient number of pixels 30 can be used in the flexible pixel strings 28 a-28 n, and the number of pixels can vary from string to string.

Flexible pixel string 28 a comprises pixels 34 a-34 n where n is the number of pixels in the flexible pixel string 28 a. Similarly, flexible pixel string 28 b comprises a number of pixels 36 a-36 n, where the number of pixels may be the same as or different from the number of pixels in flexible pixel string 28 a. Still similarly, flexible pixel string 28 n comprises a number of pixels 38 a-38 n, where the number of pixels may be the same as or different from the number of pixels in flexible pixel strings 28 a and 28 b. The flexible pixel strings 28 a-28 n may be formed into lines, curves, zig zags, or other pattern or shape as needed to form the channel letter or shaped structure 24 as desired, and the flexible pixel strings 28 a-28 n may terminate at any point within or at the periphery of the channel letter or shaped structure.

FIG. 6 and FIG. 7 illustrate a flexible pixel string 40, similar to flexible pixel strings 28 a, 28 b and 28 n of FIG. 5. Flexible pixel string 40 comprises at least one pixel 42 and at least one flexible connection 44 a-44 n. Preferably, the flexible pixel string 40 has multiple pixels 42 as shown. Each pixel 42 has lighting element(s) 46 (FIG. 7) as required for the type of display; for example, red, green, and blue light emitting diodes (LEDs) (i.e., 56R, 56G, 56B, respectively) with drive circuits 48 and control circuits 50 which could be combined into pixel unit 52 and connected with flexible connections 44 a-44 n, Other types of lighting elements with appropriate drive circuits could be used, such as incandescent or other lights, lasers, monochrome lights, liquid crystal elements, and so forth.

In the preferred embodiment, for each pixel 42, a simple control circuit 50 is included, physically attached to the pixel 42. Each flexible pixel string 40 has one or more control circuit 50/lighting, element(s) 46 combinations connected in series by flexible connections 44 a-44 n. Flexible connections 44 a-44 n include electrical, data, or activation connections which pass electrical power, graphical image data, or other activation mechanism to and from the pixel units 52. Flexible connections 44 a-44 n also include mounting or attachment connections which provide for the pixel unit 52 to be affixed in the desired arbitrary location. A single component flexible connections 44 a-44 n may provide both the data connection and the mounting connection, or multiple flexible connections 44 a-44 n may be used, distributing the data connection, mounting connection, and other connection functions among the multiple flexible connections 44 a-44 n.

FIG. 7 illustrates schematically a pixel unit 52 of FIG. 6. This example indicates lighting elements 46 which comprise red LED 56R, green LED 56G, and blue LED 56B. Each LED has a corresponding LED drive circuit 48. Each drive circuit 48 has a corresponding control circuit 50 which receives data from and through a flexible connection, for example, flexible connection 44 a. If pixel unit 52 is not the last pixel unit in the flexible pixel string 40, then control circuit 50 also passes data to flexible connection 44 b. In this example, flexible connection 44 a and flexible connection 44 b include data cables which pass image data, clock or timing signals, data latch signal, and may pass other data or electrical power as well. Control circuit 50 includes logic elements as are needed to properly activate the corresponding LED 56R, 56G or 56B, such as comparitors, counters, clocks, timers, latches, and so forth, by creating, for example, a pulse width modulation (PWM) function used to control the lighting intensity, duration, and timing for the corresponding LED. An integrated circuit 58 which comprises some or all of the elements of pixel unit 52 can be used advantageously to provide for easy and cost effective fabrication of shaped structure(s), including channel letters 24 a-24 d, in display 22, such as that of FIG. 4.

FIG. 8 illustrates standard or prefabricated pixel strings 60 with particular numbers and spacing of pixels 42 to facilitate construction of one or more channel letters 24 a-24 n of the shaped structure display 24. One would simply choose appropriate pixel strings to combine into the particular channel letter or shaped structure being constructed.

FIG. 9 illustrates display element 62. Display element 62 has some similarity to the prefabricated pixel string 60, but utilizes arrangements which could be a conventional rectangular grid of pixels 42 and pixel units 52 or arbitrary shaped pixel units 52 but with at least one flexible connection 64. Thus, the display element 62 may be positioned and oriented as needed to form a desired shaped structure 24, but does not have exclusively flexible connections between each pixel unit 52. The entire display element 62 is then used as a component, and multiple display elements 62 are used to create a shaped structure display 24 which could include a channel letter 24 a-24 d or which could be of some other shape.

FIG. 10 illustrates prefabricated display elements 66 with particular numbers and orientation of pixels 42 and pixel units 52 to facilitate construction of a shaped structure display 24 which can include a channel letter 24 a-24 d. One would simply choose appropriate display elements 66 to combine into the shaped structure 24 being constructed. A particularly advantageous approach is to utilize prefabricated display elements 66 together with flexible pixel strings 40 or prefabricated flexible pixel strings 60 to construct a shaped structure display 24 quickly and cost effectively. An additional advantageous aspect of the present invention is that the display element can be easily scaled up or scaled down in size and number of pixels. For example, the pixel unit or display element may comprise one full-color RGB or monochrome lighting element, or it can be scaled up so that each element on the flexible pixel string is an array of pixels. For instance, 2×2, 3×3, 4×4, 8×8, 16×16, 32×32, or other sized array of pixels or lighting elements can be incorporated or substituted for individual pixels or display elements. A large outdoor display could then comprise a string of large pixel arrays. The present invention provides for the utilization of large or small or intermixed pixel arrays or other shaped display elements. A particular flexible pixel string could incorporate a single pixel, a 4×4 pixel array, and a 32×32 pixel array, on the same pixel string. The hardware protocol is optimized to allow such variation, and corresponding software is optimized to enable such variation and substitution by allowing a library of pixel arrays and display elements to be created and saved. One may then simply choose and select the different pixel arrays and display elements desired, aided by software tools.

FIG. 11 illustrates schematically the addressing of pixels. Portions of flexible pixel strings 28 d and 28 e of channel letter display 22 are shown. Flexible pixel strings 28 d and 28 e are assigned a logical row to identify each flexible pixel string 28 d and 28 e. Within each flexible pixel string 28 d and 28 e, each pixel 30 is assigned a logical column to uniquely address each pixel 30. In this manner, each pixel 30 is uniquely addressable so that display controller 68 (FIG. 12) can send an image data set which will pass the appropriate image data to each pixel 30 to create a desired image even though the pixels 30 are not arranged in a standard rectangular grid arrangement. Pixels 30 on FIG. 11 are further denoted by the letter “P” in the form P (r, c), where r and c indicate a unique address.

Graphical image data 72 can be mapped from a standard rectangular array onto the logical row and logical column arrayed flexible pixel string 28 a-28 b by software. The software can accommodate scaling of data from single pixels to larger pixel arrays, such as 2×2 or 32×32 or other size pixel array, and may provide for creation and use of a library of pixel arrays and other display elements, and assist a user in selecting display elements and performing the image data mapping for the chosen display elements. Data, typically including graphical image data 72, timing data, and addressing data, are sent from display controller 68 to the shaped structure display 22, so that the shaped structure display 22 can display graphical image 26 as desired. Data sent to the shaped structure display 22 can comprise any variety of information, but typically includes any combination of color, hue, intensity, duration, timing, clock signal, and addressing data.

MODE OF OPERATION

FIG. 12 illustrates schematically the operation of a graphical display station with shaped structure display(s) 22 having flexible pixel strings 28 a-28 n. Display controller 68, which may receive data from any data source (not shown), sends corresponding graphical image data 72 to software 70 which maps the graphical image data 72 onto logical rows and columns of pixels P(1,1) to P(n,m) where n refers to the number of logical rows and in refers to the number of logical columns in each logical row. Note that the number of logical columns may vary among the various logical rows. Graphical image data 72 passes via flexible connections 74 a-74 n to pixels P(1,1) to P(n,m) of flexible pixel strings 28 a-28 n. Pixels P(1,1) to P(n,m) comprise pixel units 52 which comprise control circuits 50 and lighting elements 46, as previously described in FIG. 7. Control circuits 50 receive graphical image data 72 and cause lighting elements 46 to activate at the lighting color, intensity, and timing corresponding to the graphical image data 72 for the particular pixel. Graphical image data 72 passes via the next flexible connections 74 a-74 n to the next pixel units in the flexible pixel strings 28 a-28 n and so forth so that every pixel unit in every flexible pixel string receives graphical image data 72 and activates accordingly to create graphical image 26.
